Cocaine: How addiction develops
Permanent drug seeking and relapse after renewed drug administration are typical behavioral patterns of addiction. Molecular changes at the connection points in the brain's reward center are directly responsible for this. view more (2008-08-22)
Kids get hooked on nicotine very quickly and at very low levels of exposure
Kids get hooked on nicotine with amazing speed and at levels of tobacco that are so low that nobody had even considered it possible, say researchers in Tobacco Control. To determine how long it takes for kids to get hooked, Joseph DiFranza and colleagues followed 679 seventh grade students (aged 12-13 years) over a period of 30 months. The... view more...

Addiction: Insights from Parkinson's disease
A new comprehensive review by researchers at the Montreal Neurological Institute (MNI), McGill University and the University of Cambridge, England provides vital insights into the neurological basis of addiction by investigating Parkinson's disease patients, who in some instances develop various addictions when undergoing medical treatment. view more (2009-02-26)
Cocaine-induced synaptic plasticity linked to persistent addictive behaviors
The persistent nature of addiction is its most devastating feature. Understanding the mechanism underlying this phenomenon is the key for designing efficient therapy. Two separate studies published by Cell Press is the August 14 issue of the journal Neuron identify specific cocaine-induced changes in dopamine (DA) neurons that play a pivotal role... view more...

Dopamine study sheds new light on drug addiction
A paper published in today's issue of Science has challenged beliefs about the role of dopamine in the brain, which could lead to new treatments for Parkinson's disease, schizophrenia and drug addiction. The research suggests that dopamine has a far wider, less specialised role than previously hypothesised. view more (2005-03-02)
Team discovers possible 'Universal Strategy' to combat addiction
An international research team led by the University of Saskatchewan has discovered a signaling pathway in the brain involved in drug addiction, together with a method for blocking its action, that may point to a single treatment strategy for most addictions. view more (2006-02-13)
Animal research suggests new strategy for treating cocaine addiction
New research in monkeys suggests the feasibility of treating cocaine addiction with a "replacement" drug that mimics the effects of cocaine but has less potential for abuse - similar to the way nicotine and heroin addictions are treated. view more (2008-04-07)
New evidence on addiction to medicines Diazepam has effect on nerve cells in the brain reward system
Addictions to medicines and drugs are thought to develop over a relatively long period of time. The process involves both structural and functional changes in brain nerve cells that are still poorly understood. view more (2008-08-28)
UCSF launches study on treatment for prescription drug addiction
UCSF is launching a new study to evaluate treatments for addiction to prescription painkillers and has openings for patients to enroll. view more (2007-04-19)
Nicotinic receptors may be important targets for treatment of multiple addictions
For years, scientists have known that some people are biologically more susceptible to drug addiction than others, but they have only been able to speculate why. view more (2007-08-16)
'Erasing' drug-associated memories may stop drug addiction relapses
'Erasing' drug-associated memories may prevent recovering drug abusers from relapsing, researchers at the University of Cambridge have discovered. view more (2008-08-13)
Addiction treatment proves successful in animal weight loss study
Vigabatrin, a medication proposed as a potential treatment for drug addiction by scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, also leads to rapid weight loss and reduced food intake according to a new animal study from the same research group. view more (2008-08-21)
